Question

assertion: while walking on ice one should take small step to avoid slipping reason : this is because smaller step ensure smaller friction
choose the correct option:-
a) both A and R are true and R is the correct explanation of A
b) both A and R are true but R is the correct explanation of A
c) A is true but R is false
d) A is false but R is true​

Answer 1

Answer:

c is correct Answer of the question✓

Answer 2

The assertion is true but Reason is false. (OPTION C)

ROLE OF FRICTION IN WALKING ON ICE -

• The frictional force is the opposing force that resists motion when one surface comes in contact with the other surface.
• It depends and is calculated by the product of the coefficient of friction and the normal force (N).
• While walking on ice, one should take small steps because smaller steps produce less backward and forward force.
• If the applied force is less, more frictional force will be produced that prevent individuals to fall or slip.
• Therefore, it implies that a longer step produces less frictional force due to greater applied force and less normal force.
• Whereas, smaller steps = more friction due to more normal force and less applied force.
